IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 54,433, dated May1,1866.

- and exact description of the same, and of its construction andoperation, reference being had to the annexed drawings, making a part.of this specification, in which- Figure Iis a perspective view of theim prove ment and machine entire, and Fig. II is a crosssection of theliy-wheel and pinion, like letters referring to like parts in each.

This power is intended to be used with a chain for communicating motion.

d el represent a foundation frame-work with the friction-wheels ce, uponwhich the reel rotates. The reel is constructed by placing the spokes orbeams b b in pairs-near each other, and connecting each pair by across-piece, c, projecting beyond the points of connection with suchspokes, and putting a catch, 1 l, upon the ends of each cross-piece.These crosspieces should be equalv in length to the space between thecatches on the diiferent crosspieces, and so that the catches shall beequidistant around the reel. The reel is further strengthened by rodsconnecting the different cross-pieces f f. By this arrangement space isobtainedl between the different pairs of spokes for horses to travel andthe reel is made stron ger, as there is nearly double the number ofspokes usually obtained. Thereel also may i be made smaller and thecatches for the chain nearer together than when placed upon thc ends ofthe spokes, and, of course, there is less trouble from slack chain.

lb h are cross I'oundationtimbers connected by the ties r 1". Betweenthese rise the supportst' z', diagonally crossing and bracing eachother.v At their intersection is the pin upon which the iy-wheel andsmall reels connected therewith run. Upon the top of these diagonalsupports is placed the timber j, held in position by screws lc k,passing through slots in said timber. From the point a on said timber issuspended the swingpulley o, witha Swivelioint at which holds up thechain as it comes off the small reelsp p by the point at fm and swivelat w. It accommodates itself to the chain Whether upon the larger orslnaller of the small reels.

lis a weighted lever with fulcrum at w, the hither end bent downward andsustaining the pulley m, which guides the chain in its passage to thesmall reels. By means of the lever the pulley is pressed or drawn towardthe large reel and the chain kept taut. By a pin at y this pulley isadjusted to carry the chain onto the larger or smaller of the smallreels. After the apparatus is set for operation the chain is tightenedor loosened by moving forward or backward the adjustable timber orcap-piece j, with which the pulleys o and m also move.

p p are different-sized reels attached to the iiy-wheel q, by using oneor the otherof whichy greater or less motion is obtained in theflywheel.

q is the liy-Wheel, with the Small reels pp ruiming upon a section of acone, R, with its base outward. This cone screws into the pin s. If theHy orfconejjwear, by turning the cone on the pin s the cone is carriedforward by the screw on the pin, and the joint made by the cone and thefly is made as tight or close as desired. Ihe base of the cone beingoutward,itprevents theHy-Wheel from running off.

What I claim, and desire to secure by Letters Patentis- 1. Thearrangement, in the large reel, of placingthe Spokes in pairs andconnecting them by cross-pieces which shall extend beyond the spokes, asand for the purposes described. A 2. The weighted lever l, incombination with the pulley m.

3. The adjustable cap-piece f, in combination with the pulley m andlever l, subst-antially as described.

4. rIhe combination of the wheel G, cone R, and reels p p, when the Sameare arranged and operate substantially as above described.
